Lower Devonian graptolite fauna 'from the Bardo Mts (Sudetes)
ABS'IlRACT: PTel:iminary results of !i'IlvesrbiJgatioos, of :the g:ralltoU.te fa.una from the Zdan6w pr1Oc1lUe .in Ute l3&'do Mt& are here pne6IeIlIted~ Mo&t 'Of tihe ~ fotmd there are 'forrthe first time ;repoIl'ted from Poland.
The presence of Lower Devonian graptolites mn' the black siliceous shales in the norrthern part of the 2dan6w p~fi1e was first reported by Jaeger (1959) Who, on
the
basis of samples housed in Berlin, identified Mcmograptus praehercynicus Jaeger and Mcmograptus microdcm silesicus Jaeger. The graptolites found in this part of the 2dan6w profile by Teller (1960) were referred to Monograptus hercynicus Pernerand MonograptuB cf. hemiodon Jaeger. According to the then currently reCognized views.both above awthol's accepted the upper.ni.ost SHurian age of 1he graptolltes just mentioned.
Detailed investi8ations of the northern part of the 2dan6w profile were undertaken by the writer in 1975/1976 under the inspiration and scientific guidance of L. Teller. They have provided very rich material sufficing for the determination of a complete sequence from the Mono- graptus uniformis Zone to the Monograptus fariicus Zone including.
The following species have been identified from the stratigraphically oldest Lower Devonian profile within the M. uniformis Zone i.e. M. unifor- mis uniformis ffi'byl, M, unifonnis angustidens Pfibyl, M. uniformis paran- gustidens Jackson & Len.z, M .. aequabilis aequabilis Pfibyl, M. microdon Reinh. Richter and Linograptus 'posthumus posthumus (Reinh. Richter).

f1?e. younger - M. hereynicUB Zone - contains such species as M~ h~cYnicus subhercynicus W:illefert and M. aequabilis aequabilis Pribyl.
Like in the Urals (Koren 1973, 1975) the successively younger Zone is indicated by M-onograptus· fcilcarius Kor·eh. This index fomn is accom- panied by M. aequabilis notoaequabilis Jaeger· & Stein and
M:
telleri Jackson··& Lenz. The two latter species also occur in the M. fanicus Zone, the yo~gest one so far observed inthe
·profil.e under . consideration.Mo~t of the species mentlioned above has not as yet been reported from
.beds'
of the same age in Poland. M. angustidens. (Teller 1964, Tom- czyk 1968), M. t1:niforrnis. (Korejwo & Teller 1964) and M. hercynicus· (Teller 1960) l;U'e the only exceptiaris.The continuous stratigraphic sequence· and the morpholOgical fe- a·tures of the fauna here considered, as well as the presence Qf interesting transition forms, have all helped relaiively thoroughly to irace the phylogeny of the Whole Lower Devonian graptolites assemblage enco- untered by the Wl'Ii.ter. This assigns to ~the above profile a position of.
particular significance among the European profiles of t~ same age.
The· folloWing 'evolutiJOrimy lliles have • been differentiated .·on the basis of now availabl.e ,in.ve~tigation ~dilta" M. un,iformis; M. hercynicu.s subhercynicus - M. falcarius; M. hercynicus subhercynicus - M. telleri·
and M. aequabilis

studies may ~uggest some amendments.
